Post-traumatic contractures of the foot as well as of the hand were described by Volkmann himself but, in spite of the considerable literature concerning the aetiology and treatment of the upper limb contractures which go by his name, the subject of ischaemic deformities of the leg has received comparatively little attention. The following paper briefly reviews the features of this well defined...

Leaping, parachuting and gliding are the primary means by which arboreal squirrels negotiate gaps in the canopy. There are notable differences among the three locomotor modes with respect to mid-air postures and aerodynamics, yet it is unclear whether variation should also be expected during the launch phase of locomotion. To address this question, launch kinematic profiles were compared in lea...

The purposes of this study were to 1) investigate the sequence of development of head, upper extremity, and lower extremity extension in the prone extension posture in healthy infants; 2) identify the variations in the sequence; and 3) compare these postures within the sequence with the development of prone-on-elbows and prone-on-hands postures. Twenty healthy, full-term infants were observed l...

BACKGROUND Osteoprotegerin (OPG) is a member of the tumor necrosis factor receptor superfamily and suggested as a marker of atherosclerosis. However, little is known about the association between plasma OPG levels and lower extremity arterial disease. We investigated whether plasma OPG levels were associated with the presence and severity of lower extremity arterial disease in patients with typ...

We examined the effects of singular versus dual task constraints involving upper and lower extremities in typically developing children in young (4-6 years old), middle (7-9 years old), and old (10-13 years old) age groups. The purposes of this study were: 1) to investigate the effects of singular upper and lower extremity and dual upper and lower extremity conditions on motor variability and 2...

INTRODUCTION The idea of establishing an examination that accredits the training of the specialists in orthopaedic surgery at the end of their educational period as residents is subject to controversy. With the aim of encouraging the development of this examination, the present members of the National Commission of the Specialty of Orthopaedics (CNE) have reviewed the results obtained in previo...

An unusually wide pneumatic tourniquet has recently become available; we provide a simple formula for its use with a low but effective inflation pressure. A prospective, randomised and controlled trial in 600 lower limb and 150 upper limb operations is reported. The wide tourniquet (12.5 cm) was as effective at low pressure as was a conventional tourniquet (9 cm) inflated to significantly highe...
